This invention ,relates 'to' Stoppers 4for water bottles or other receptacles, and aims to provide certain improvements therein."

The invention is particularly directed to! ward a cheap and `eiiicient'form of stopper which shall have the necessary .strength and` rigidity, and which shall form an adequate.

closure for the hot water bag or other device to which it is applied., It alsoprovidesA certain other improvements which may be advantageously availed of, and which .will j, be hereinafter m'orefullydescribed.

In theV drawings, wherein 'Ihave shownthe preferred form of the invention',

Figure l is adiametrical section of the upper part of ahot water bag, showing the invention as applied thereto.

Fig. 2 is a similar section of a stopper member of the type shown in Fig. l, on a larger scale, and provided with a swivel packing.

Fig. 3 shows the adaptation ofthe swivel packing to the conventional type of stopper.

Referring first to Fig. l, let A indicate the hot water bag or other receptacle, and B a socket member usually formed of sheet metal and having an inwardly turned flange C which constitutes in eifect the valve seat against which a leak-tight joint is made by the packing washer of the stopper.

rIhe stopper proper according to the present invention comprises acup D, closed at its bottom, and open at its top. The invention provides the standard form of wire handle E, such as is used on more expensive types of Stoppers, the handle in the present instance being carried down through the cup of the stopper and joined to the bottom F thereof. The joint may be made in any approved fashion, but I prefer to rivet the ends of the wire to the bottom wall by perforating the bottom wall and'countersinking the hole so that the ends of the' jection is substantially "cylindrical,A but is attened downinto slightly t'apered :for-in `to,

engagev the tapered inner wall of the plate.

' Bythi's consta/'nettion 'very satisfactory and efficient form of `stopper is made 'at very little expense. The cup, vof which the stopper is formed, is made preferably 4of thin sheet metahand its side `walls are provided with'A '1 rolled-threads 'to engage'lthe threads the socket member B. It'wifll be understood that the'` resistance to the/screwing,in'of 4tlie f stopper is primarily near the point of edn'- tact b'etwe'n the packing land?"seat,` and the` arranger-.Lent of the handle with its "e'ngage j ment 'at' the lower w'alljoftlie 'stoppe`rfen-- ables the forcefof-screwingthev stopper't be applied as nearly as possible at the point of greatest'resistance, Without having to be transmitted through the side walls of the stopped. This permits a reduction of the necessary thickness of the stopper, so that the whole construct-ion, while strong and rigid, can be made of very thin gauge metal. In Fig. 2 I have illustrated the stopper with a swivel connection. In this case the metal E is riveted to the bottom wall F, as before, but the projection L is omitted from the cup. Around the outer edge of the cup is formed a groove M, in which is turned the edge of a swivel plate N, which carries the packing washer. The swivel plate is provided with a Vprojection L, entering the aperture in a plate J, which retains thev f permits a free and adequate swivelling.

This feature of the invention is not neces sarily limited to the construction shown in Fig. 2, since it may be applied to other forms of stopper, as for instance, that illustrated in Fig. 3, where it shows the standard or conventional type of stopper.

While I have shown and described several forms of the invention, it will be understood that I do not wish to belimited thereto, since various changes may be made therein without departing from the spirit ofthe invention.

What I claim is 1 l LA stopper for `hot water bottles or the like, comprising a cup open at its ltop and a handle passing downwardly through the open top end andconnected with the cup VWall and riveted to the latter.

3. A stopper for hot Water bottles or the like, comprising a cup formed of sheet metal, the side Wall of which yis screw-threaded, and said cup having a bottom Wall, a Wire handle passing downwardly through the cup and riveted to said bottom Wall, and a packing carried by the bottom Vof the stopper.

4. A stopper for hot Water bottles or the like, 'comprising a cup formed of sheet metal having a closed bottom and an exterior groove in its side Wall, a plate having its edge turned into said groove and swivelling with regard to thecup, and a packing carried by said plate. Y

5. A stopper for hot Water bottles or the like, comprising a bod member having an exterior groove in its side Wall, a plate having its edge turned into said groove and swivelling with regard to the body oit' the stopper, a packing carried by said plate, a tapered plate overhanging said packing, said tapered plate having a groove, and a projection on said first-named plate entering the groove in said tapered plate and holding the latter connected to Athe former.

6. A stopper for hot Water bottles or the like, comprising an open cup formed of sheet metal and having a closed bottom Wall, a Wire handle having flanges resting on the top of said bottoni Wall,A theeridsV of said handle passing through saidv bottom Wall andbeing riveted on the opposite side of said Wall to said flanges, said cup having a groove in its side Wall, a svvivelled plate contacting With said bottom Wall, and having its edge turned into said groove, a tapered plate carried by said swivelled' plate, said tapered plate having a lateral flange, and a packing located betvveenthe swivelled plate and the flange of said tapered plate.

In witness whereof, I have hereunto signed'my name.
